如何使用php获取网站的CSS [关闭]

Question

I wanted to find colors from a website using php,

I can fetch the source code of a website but not able to fetch css files of a website,

is it possible to fetch external css of website,

Thanks,

Fetch the Website, search with a Regex for the CSS, fetch the CSS, search with a Regex for the Color Codes in the CSS. You must get the filename of the CSS from the HTML-Page to fetch it. There ist no way to do this automatically, except a manual search.
